California, March 14, 2016 -- True Circuits, Inc. (TCI), a
leading provider of analog and mixed-signal intellectual property (IP) for
the semiconductor, systems and electronics industries announced today the
availability of a new line of Phase-Locked Loop (PLL) hard macros
specifically tailored to the stringent power requirements and wide frequency
operation range of the rapidly-growing IoT market. Sipping only 45uW at
30MHz and running from core power, the "IoT PLL" is designed for very low
power. With multiplication factors up to 8192, the PLL is able to run off
of a small and inexpensive 32KHz crystal and still clock a 32-bit CPU at up
to 250MHz. The IoT PLL is ideal for applications like wearables and senor
devices, where the power-performance profile must be managed tightly, and
possibly over a very wide frequency range. The PLL is delivered as a single
hard macro, and is available in a variety of TSMC, GLOBALFOUNDRIES and UMC
"Designers and architects of IoT products are faced with difficult tradeoffs
when managing power, so being able to operate clocks as low as 32KHz, and
any place in between, is important", remarked Brian Gardner, True Circuits,
Vice President of Business Development. "A low power heartbeat mode can
also be valuable, and stepping up into various power-performance points can
allow for fine-grained power management. 32KHz crystals have been used in
watches for decades, so they are small, cheap and available in endless
variety. With its wide range, low power operation and ease of integration,
our versatile IoT PLL is well suited to meet the many challenges of IoT
Price and Availability
True Circuits IoT PLLs are available in TSMC, GLOBALFOUNDRIES and UMC
processes from 65nm to 28nm. Customers can license TCI timing IP either
directly from TCI or through its global network of design services partners
and sales reps. The hard macros are available for a per use license fee and
no royalty fees. The license fee includes integration support from TCI and
its partners to ensure a successful customer tape out. The deliverables
include GDSII and LVS Spice netlists, behavioral and synthesis models,
Library Exchange Format (LEF) files and extensive user documentation.
About True Circuits PLLs and DLLs
In addition to the new IoT PLL, True Circuits offers a complete family of
standardized and silicon-proven General Purpose, Clock Generator, Deskew,
Spread Spectrum and Ultra PLLs and DDR DLLs that spans nearly all
performance points and features typically requested by ASIC, FPGA and SoC
designers. These high quality, low-jitter PLL and DLL hard macros are
suited to a wide variety of interface standards and chip applications. They
are pin-programmable, highly process tolerant and reusable. They are also
easy to integrate and are fully supported, so customers can reduce both
design and silicon risks.
True Circuits PLLs support a wide range of frequencies, multiplication
factors and functions over which they deliver optimal performance, avoiding
the cost and complexity of licensing multiple point-solution PLLs from
foundries or other vendors. TCI's DLLs are available in mutli-slave and
multi-phase versions and different sizes and form factors. They delay a set
of signals by precise and adjustable fractions of a reference clock cycle
independent of voltage and temperature and are ideal for high-speed DDR and
ONFI interface applications. Customized PLL and DLL solutions are also
available for specialized chip applications.
True Circuits PLLs and DLLs are available for immediate customer delivery in
TSMC, GLOBALFOUNDRIES and UMC processes from 180nm to 16nm. For more

About True Circuits DDR PHYs
True Circuits also offers a high performance DDR 4/3 PHY that is a
high-performance, scalable system using a radically new architecture that
continuously and automatically adjusts each pin individually, correcting
skew within byte lanes. This state-of-the-art tuning acts independently on
each pin, data phase and chip select value. Read data eye and gate timing
are also continuously adjusted. Automatic training is included for
multi-cycle read gate timing and write leveling, write data eye timing, and
internal and external (on DRAM) Vref setting.
The PHY employs a localized and optimized PHY-to-memory controller interface
to ease timing closure. The circuitry in each pin is able to measure the
data eye and jitter, and calculate flight delays. The PHY also includes a
full speed read/write BIST, which tests the complete read and write paths of
every pin simultaneously with pseudo-random data.
Remarkable physical flexibility allows the PHY to adapt to each customer's
die floorplan and package constraints, and is delivered and verified as a
single unit for easy timing closure with no assembly required. The PHY is
also DFI 3.1 compliant, and when combined with a suitable DDR 4/3 memory
controller, a complete and fully-automatic DDR 4/3 system is realized.
The True Circuits DDR 4/3 PHY is initially available for customer delivery
in TSMC's 28nm HPM/HPC process. The PHY will be available in additional TSMC
and GLOBALFOUNDRIES processes in the very near future. Interested customers
